GENERAL ELECTRIC COMPANY, OF SCHENECTADY, NEW YORK, A CORPORATION OF iNEW YORK ATTACHMENT rLuG CAP application med .Tune 7, 1926. seriai no.114,aoo.

This invention relates generally to a connection .terminal forelectrical cords.

It is an object of this invention to devise a connection terminal for acord which will be practically indestructible.

It is a further object of this invention to devise a connection terminalwhich 'will' be sealedv against external vapors and liquids.

It is another object of this invention t`o lo devise a novel connectionterminal which will incorporate aresilient insulating material such as.rubber.

It is a further obiectY of the invention to devise a cord terminal whichwill have no exposed screws or bare wires and which will not becomeshort circuited.V

appear from the following description in which I have set forth thepreferred (emvl 2o bodiment of my invention. Itis to be understood thatthe ap ended claims are to be accorded a range o equivalents consistentwith the state of the prior art,

My invention is illustrated in the accompanying drawing forming a partof this application, in-Which- Fi ure l is a longitudinal sectionthrough the evice,.

Figure 2 is a section along thelline of Figure '1, Y

F'gure 3 is a front elevation of the, device, v and Figures 4 and 5 areviews similar to Figure 3, but showing the terminals o\the cap indierent positions.

In` carrying out my invention I provide a cable l, which houses twoinsulated wires 3 and 4. Terminals 5 and 6 of the shape shown in Figure2, are carried by al1/insulating housing 7, and are connected to thewires 3 and'4 in a manner now to be described. s A

Each terminal hasv an eyelet 8 around which the insulated wire iswrapped'one or two revolutions. y wrapped an kadditional number of turnsaround the portion of the terminal forming the eyelet, and is thensoldered to the terminal. I have found that the portion of the wiredisposed adjacent to thesoldered The bare wire is then point will notieX so readily, and it is for this reason that I have provided a numberof turns of' Wire to ermit relative movement of the termina With-respectto the wire, Without the wire becoming broken through use.'

After the Wires 3 and 4 have been wrapped y around thir respectiveterminals 5 and 6 in the manner just set forth, a core 9 is forcedthrough the eyelet 8 and spaces the terminals 5 and 6 the requireddistance apart. The casing 7 is now set into place and is vulcanizedtothe core 9. It Will therefor appear that the terminals 5 and 6 arecompletely surrounded by rubber. The casing 7 has a sleeve 10 i whichencloses the cable 1 for a slight dis- The further objects of theinvention will tance.

From the foregoing description of the,

ll should be a greater distance apart than the distance between "theterminals 5 and 6,

the casing? could be depressed in the man' ner shown in Figure 3,whereupon the terminals 5 and 6 would be moved the required distanceapart, thus permitting the cap to be inserted in the plug. The cap 7would be depressed in the Imanner shown in Figure 5 in case the openingsin the plug 11 were close together.

The casing 7 is made of rubber and prol vides a casing which performs athreefold function, in that the casing insulates the terminals 5ian'd 6from each other, it permits the terminals to be moved toward lor away.from each other, and it also yieldingly holds the terminals together,thus `exerting a suiii-` cient force for causing the cap 7 to be securedto the plug 1l. f t

I claim:

l. A. device of the type described, comprising a cable carrying wires,terminals having eyelets at one end thereof, said wires being wrappedaround' said eyelets, an insulating and resilient core passed throughsaid eyelets, and an insulating and resilient casing securing said coreand said terminals to seid cable. I

2. ln a resilient terminal, a resilient body of insulating material,a'pair of spaced contact strips having their ends embedded in theresilient material of the body whereby the exposed ends of the Contactstrips may give relative to each other due to the resilient nature ofthe body, and a single anchoring memm ber embedded in said body andconnected to the embedded ends of kboth strips.

lin testimony whereof I aiix my signature.
